Colombia's COE: How Coffee Excellence Is Crowned

Every spring, deep in the Caribbean coastal town of Santa Marta, Colombia, a global gathering of coffee experts converges—not to sip lattes, but to crown the single best lot of Colombian-grown coffee through a meticulous and high-stakes process known as the Cup of Excellence, or COE.

In a single day, expert judges evaluate over 29 coffees blindly, tasting around 10 samples each, all brewed identically with 11.5 grams of ground coffee per cup, with a margin of error of just 0.01 gram. Over three intense hours, they eliminate half the entries—ultimately selecting Colombia’s top-scoring beans and crowning one champion.

What Is the Cup of Excellence?

The Cup of Excellence (COE) is an annual competition that began 12 years prior in Brazil and has since expanded across Latin America, including Colombia and Rwanda. Organized by the Coffee Quality Institute and supported by international importers, roasters, and cuppers, COE is designed to identify and promote the highest-quality single-origin coffees through blind tasting, online auctions, and global exposure.

Judges—certified Q Graders trained in sensory analysis and quality control—participate in a rigorous elimination round. Starting with 513 submissions from Colombian farms in 2011, the field narrows through multiple rounds until the top 10 are chosen. The very best of those is named the Champion Coffee, often selling for extraordinary prices at auction.

How Are the Coffees Judged?

Judges assess each coffee blindly—without knowing the farm, region, or processing method—focusing on attributes like aroma, acidity, balance, sweetness, and aftertaste, scored on a scale from 1 to 8 in each category. Brewing follows a standardized protocol: 11.5 ± 0.01 grams of coffee per 150 ml cup, brewed at precise temperatures, with identical white cups and no identifying markers.

The process begins with a sniff-based aroma evaluation. At exactly 240 seconds after pouring water heated to 200°F (93.3°C), judges use specially designed deep-bowl spoons to break the crust of floating grounds, releasing aromatic vapors while carefully skimming away residue. This “break” moment is critical for scoring fragrance and aroma before the actual tasting begins.

Tasting follows an intense protocol: judges slurp coffee forcefully to aerate it across the entire palate, evaluating flavor, body, and cleanliness. They then spit out the coffee to avoid palate fatigue and maintain scoring accuracy. Sounds range from sharp intakes to comical bursts—reminiscent of “a group of five-year-olds blowing party whistles,” as one judge described the din. Every score is recorded, debated, and defended in private sessions following each round.

Who Were the Key Players in 2011?

That year, judges included internationally acclaimed cuppers such as Albert Tégolo from Norway (Q Grader and cupping expert), Geoff Watts of Chicago’s Intelligentsia Coffee & Tea, Brazilian and Japanese specialists, and sensory scientist Paul Songé from UC Davis. Also present were representatives from global coffee companies like Solberg & Hansen of Norway.

The panel operated under strict anonymity protocols. Even the water girls—dressed in uniforms adorned with the COE logo—played a crucial supporting role, pouring water heated to a precise 200°F into identical cups using silver kettles. Their synchronized movements added ceremonial flair to the scientific rigor of the process.

What Happened in the 2011 COE Finals?

After days of eliminations, the final 10 coffees were scrutinized further. Judges described entries with vivid metaphors: “chocolate, licorice, cream candy,” “cooked banana with rhubarb and hibiscus,” and even “blackberry, plum, and breadfruit.” One coffee, number 8, was dismissed as “very simple” by Watts, despite initial hopes.

The winning coffee came from Finca La Loma, grown by Arnulfo Leguizamón, whose lot scored an exceptional 94.05. Described as having “passion fruit acidity” with “almond, lemon verbena, jasmine, and tamarind aromas,” the cup exhibited creamy, caramel-like body with lingering notes of wildflower honey. It was later auctioned at over $40 per pound, reaching up to $260 per kilogram in Japan.

Leguizamón, dressed sharply for the occasion, remained humble amid the celebrations. When asked how he’d use the prize money, he simply said, “Thank God and the Virgin Mary—I can pay my debts.” Weeks later, he announced plans to plant Castillo, a variety developed by Colombia’s national coffee research body, despite some controversy over its taste compared to traditional varieties like Bourbon and Caturra.

Why Does Coffee Flavor Vary So Much?

Coffee flavor is shaped by more than just genetics. Altitude, volcanic soil, harvest timing, processing methods (washed, natural, honey), drying techniques, and roasting all play vital roles. In Colombia, the rugged Andes Mountains provide ideal conditions: elevations between 800–2300 meters, consistent cloud cover for filtered sunlight, and stable humidity that slows bean maturation and enhances aromatic complexity.

The 2011 COE controversy over Finca La Loma highlighted debates about variety authenticity. Though initially thought to be a unique local cultivar, an investigation found the winning coffee had around 30% genetic overlap with Castillo, a disease-resistant hybrid promoted by Colombia’s Federación Nacional de Cafeteros (FNC). The debate underscored tensions between commercial viability, disease resistance, and traditional flavor preferences.

Frequently Asked Questions

What is the Cup of Excellence (COE)?

The Cup of Excellence is an annual international competition that identifies and promotes the best single-origin coffees through blind tastings, expert judging, and online auctions. It started in Brazil and now runs in multiple coffee-growing countries, including Colombia.

How are coffees judged in the COE?

Coffees are evaluated blindly based on aroma, flavor, acidity, sweetness, balance, aftertaste, and overall cup quality. Each attribute is scored from 1 to 8, using standardized brewing protocols with 11.5g of coffee per cup. The highest-scoring lots advance to finals and are auctioned globally.

Who are the judges in the COE competition?

Judges are certified Q Graders and specialty coffee experts from around the world. They include roasters, importers, sensory scientists, and cupping professionals who have undergone rigorous training in coffee quality assessment and sensory analysis.

What makes Colombian coffee unique?

Colombian coffee is grown across the Andes Mountains at high altitudes (800–2300m), with fertile volcanic soils, consistent cloud cover, and cool temperatures that slow ripening. These factors contribute to dense beans with complex acidity, sweetness, and aromatic depth.

Why was the 2011 winning coffee controversial?

The champion coffee from Finca La Loma was initially thought to be a unique local variety but was later found to share around 30% of its genetics with Castillo—a disease-resistant hybrid promoted by Colombia’s coffee federation—sparking debate over taste, variety authenticity, and farming priorities.

How much can COE-winning coffee sell for?

In 2011, the COE-winning coffee from Finca La Loma scored 94.05 and was sold at auction for over $40 per pound, with prices reaching up to $260 per kilogram in Japan, highlighting the premium fetched by top-rated specialty beans.
